Oct 2026Series BARCH Venture Partners (lead); Bezos Expeditions (lead); General Catalyst (lead); Index Ventures (lead); Khosla Ventures (lead); Spark Capital (lead)$475M$5.4BOratomic, a Pasadena-based company building fault-tolerant quantum computers with neutral atoms, raised $475 million at a $5.4bn valuation in a round reported by The Wall Street Journal on 8 October 2026. The round came three months after the company's Series A and lifted its valuation from $1.5bn. The $300 million Series A announced in July 2026 was co-led by ARCH Venture Partners, Spark Capital and Khosla Ventures. The company was founded in 2025 and emerged from stealth on 31 March 2026. Oratomic says it is building the world's first utility-scale quantum computers, enabled by a new regime of ultra-efficient error correction that uses only light and atoms. Its team integrates expertise in quantum error correction, neutral atom systems, artificial intelligence and optical engineering, and the company says it aims to make fault-tolerant quantum computing a reality.

The round was co-led by ARCH Venture Partners, Spark Capital, and Khosla Ventures, with participation from Bezos Expeditions, Index Ventures, General Catalyst, Lowercarbon Capital, Bain Capital, Formation, Nebular, and individual investors including quantum researchers David and Scott Aaronson. The company issued convertible preferred shares as the deal structure. Oratomic aims to develop a fault-tolerant, utility-scale quantum computer capable of reaching commercial utility before 2030, leveraging a research claim that Shor’s algorithm could run on 10,000–20,000 neutral-atom qubits instead of the traditionally assumed 1 million. The $300 million provides approximately four years of runway for quantum hardware fabrication, fault-tolerant algorithm research, and hiring physicists and engineers. This is the largest Series A ever raised by a neutral-atom quantum computing company. Oratomic emerged from stealth three months prior, having raised a seed round from Nebular in December 2025 and publicly launching March 31, 2026. The startup was founded by Caltech physicists and operates in the competitive neutral-atom space alongside Infleqtion.
